BROOKLYN, New York, Tuesday, July 6, 2020 - Over the past 30 years, the use of glass- and carbon- fiber reinforced composites in aerospace and other high-performance applications has soared along with the broad industrial adoption of composite materials.
GAINESVILLE, Fla. --- In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as the tropics. The finding runs counter to a long-held hypothesis that tropical regions, home to the planet's richest biological diversity, outpace their temperate counterparts in producing new species.
Whether it's on top of a self-driving car or embedded inside the latest gadget, Light Detection and Ranging (lidar) systems will likely play an important role in our technological future, enabling vehicles to 'see' in real-time, phones to map three-dimensional images and enhancing augmented reality in video games.
The challenge: these 3-D imaging systems can be bulky, expensive and hard to shrink down to the size needed for these up-and-coming applications. But University of Colorado Boulder researchers are one big step closer to a solution.
There's a fairly large flaw in the way that programmers are currently addressing ethical concerns related to artificial intelligence (AI) and autonomous vehicles (AVs). Namely, existing approaches don't account for the fact that people might try to use the AVs to do something bad.
For example, let's say that there is an autonomous vehicle with no passengers and it is about to crash into a car containing five people. It can avoid the collision by swerving out of the road, but it would then hit a pedestrian.
It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields. Scientists at the National Institute of Standards and Technology (NIST) have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously. Together, these measurements can uncover new knowledge about a wide range of special materials that are crucial for developing the next generation of quantum computers, communications and a host of other applications.
The development of metasurfaces opened a horizon for the advance of planar optics. Among various metadevices, the metalens has attracted widespread attention for practical applications in imaging and spectroscopy, where it allows multifunctional wavefront manipulations for improved focus.
Teenagers who prefer to stay up late at night and sleep in late the next day are more likely to develop asthma and allergies than their "early bird" counterparts, according to new research published today.
Researchers in the Cockrell School of Engineering at The University of Texas at Austin have built a new type of battery that combines the many benefits of existing options while eliminating their key shortcomings and saving energy.
More than 40% of energy consumption in the European Union is by buildings and 63% of this figure is due to residential dwellings. Furthermore, more than 75% of domestic energy consumption is related to heating and the production of clean hot water. These data highlight the need to look for alternative sources of energy in line with the EU's 2030 targets that seek a sustainable transition from fossil fuels to renewable energies and to reduce emissions of greenhouse gases.
Scientists have made a pivotal breakthrough in the important, emerging field of spintronics - which could lead to a new high speed energy efficient data technology.
An international team of researchers, including the University of Exeter, has made a revolutionary discovery that has the potential to provide high speed, low power-usage for some of the world's most well-used electronic devices.
Superconductivity is a physical phenomenon occurring at low temperatures in many materials which manifests itself through a vanishing electrical resistance and the expulsion of magnetic fields from the material's interior. Superconductors are already used for medical imaging, fast digital circuits or sensitive magnetometers and hold a great potential for further applications. However, the conductivity of the majority of technologically important superconductors is in fact not "super".
The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems.
Lithium ion batteries (LIBs) have many advantages but there are much more abundant metallic elements available such as sodium, potassium, zinc and aluminum.
An international study has used data from a major home Internet Protocol (IP) security camera provider to evaluate potential privacy risks for users.
IP home security cameras are Internet-connected security cameras that can be installed in people's homes and remotely monitored via the web. These cameras are growing in popularity and the global market is expected to reach $1.3 billion by 2023.
Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak?
A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden "biofilms" that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
Miami, FL--Your doctor tells you that you need a statin to lower your cholesterol and reduce your heart attack risk. You don't like taking medicine and your friend tells you that he had achy muscles after he started a statin. You wonder if you should listen to your doctor or go without the medicine. An article just published in Mayo Clinic Proceedings by Dr. Carl E Orringer of the University of Miami Miller School of Medicine and Dr. Kevin C Maki of Indiana University's School of Public Health may help your doctor to make the right decision.
